Subject: respect Proxy-To-Originating-Realm in request_coa_originate()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=29cf4b3e01bb09f8c2cf310735ad61146f74e51e;p=thirdparty%2Ffreeradius-server.git

respect Proxy-To-Originating-Realm in request_coa_originate()

this isn't entirely the correct name for how we use the attribute,
but it's at least consistent with the rest of the server.
